You mount your artwork too high. Should be only 4-8" above the back of your sofa.

I'd consider painting the back wall. The mirror seems too large for this room.

You have a good start, you just need to add more layers.

Lamps, console tables, end tables, throw pillows, etc. will all add interest to the room. Right now you seem to be relying on the wall to make the room look more finished. It's just one piece of the puzzle.

@deegw. Thank you. Should I add a console table directly behind sofa or at wall. There is a little more than 4 feet behind the sofa.

Agree with Beverly. Artwork needs to be lower

Thank you. I will definitely lower the artwork. I'm thinking I should add more art also. What do you think?

Some idea to go with console table with 1-2 side lamps

I don't necessarily agree that the art has to be lower, but would only be able to determine that if I was standing in the space, specially when the sofa is 4 ft away.

I think you are trying to make the arrangement too symmetrical with one pair and then two different pieces. You are trying to add a pattern when there shouldn't be one. More pieces would help.

Art can be as high or low as you want. You are looking for balance.

Not every piece of art has to be at "eye-level".

Such great suggestions. Thank you all and keep them coming!

Also, due to my technical backgound (I think), I struggle with randomness. That's why my gallery wall looks the way it does.

You can also mix art with collected pieces.

I have this Moroccan doorknocker mixed in with my art. It is about 12" high.

I suggest you choose and place the sofa before you start hanging art on the wall.

this:

a bit more color and gallery lay out. right now yours are all linear. try something like this

a long sofa table or console would do wonders

Lower the art work though. from the floor to CENTER of the picture should be 56"-60"

other console ideas

you could try some framed prints (similar color, style and frame) like this

IMO original art needs to stand alone and galleries do not hang a bunch of stuff together on a wall with no connection to eachother Like maybe the same artist . Hang the 2 large pieces above the sofa find other places for the rest . Yes to lowering the art and 4' is pretty narrow to add a console table .Maybe show us whay the space behind the sofa is 4' THe mirro makes no sense on thta wall . I do agree get the new sofa then hang the art. and adding a biunch of misc. stuff will not make it better IMHO

I do agree with the posters who are showing the long console table behind the sofa and against the wall.. Would also recommend some end table for your sofa as well as a coffee table and additional seating and a rug.

@Patricia Colwell Consulting, the wall would look REALLY bare if I only hung the 2 large pieces.

I had a friend that was an art major and worked in the art industry. She had been collecting art since she was young and had a large collection. Her house had art on every wall, from floor to ceiling ... I'm not exaggerating! I couldn't live with that much art/stuff, but my house always felt very bare after visiting hers, even though I had art on several walls, but barely anything compared to her collection.

Some people like the look of many pieces arranged gallery style and some don't. Neither is right or wrong, just personal preference.

There is nothing wrong with a large wall and seperate pieces of art hung on that wall. I had a 30' long hallway in my last house have 7 pieces of art hung there between doorways and loved it it made the hallway feel like agallery .Maybe what you need is more art . I have frieund who aslo collests art but instaed of hanging every piece in his small home he rotaed pieces all the time . I think a trip to a gallery or art college is what you need to do then worry about where to hang the art . We see only one wall in your space , have no idea of the size od anything so limited info is all we have. I will say to add all that stuff behind the sofa ia just all wrong . Did you buy the art because you love it or becuase it matched the sofa ? If you were my client that would be my first question.. I lkke the pieces but I need to see the whole space please

You need more art. These 4 pieces are never going to work well in a group by themselves. The scale isn't quite right.

I rotated the diptych and placed the other two pieces, but the sizes just don't quite work. You would need to fill in with some more art/objects.

You can easily re-wire the back or move/add new hanging hardware to turn a piece from portrait to landscape.
